Back body triangle
Also known as Back Triangle — the canonical term used on this site.
Training background: Distinguishes from the rear triangle — not always consistently applied
Disambiguator — distinguishes from the rear triangle choke
Back body triangle is the disambiguating label sometimes attached to the back triangle when distinguishing it from the rear triangle choke — both attacks from the back position, but mechanically distinct (the back triangle is an arm-in strangle; the rear triangle is a neck-and-arm leg-triangle).
Etymology. The “body” qualifier flags the configuration as a body-encircling triangle rather than a neck-encircling one. The disambiguator is used in coaching contexts that need to clarify which back-position triangle is being discussed; in less ambiguous contexts, “back triangle” alone is the standard label.
Mechanics. The back triangle compresses the carotid arteries bilaterally using the leg-triangle structure that closes around the opponent’s neck and trapped arm — the connection through the closed leg loop maintains the compression as the opponent rotates to escape.
Cross-reference. “Rear triangle” attacks from a similar position with different mechanics; “arm-in back choke” is the descriptive functional name. Full mechanical coverage on Back Triangle.
